Each piece of money is a mere coin, or means of circulation, only so long as it actually circulates. Karl Marx
All motion is cyclic. It circulates to the limits of its possibilities and then returns to its starting point. Robert Collier
Capitalism is dying and its extremities are already decomposing. The blotches upon the surface show that the blood no longer circulates. The time is near when the cadaver will have to be removed and the atmosphere purified. Eugene V. Debs
A house sold by A to B does not wander from one place to another, although it circulates as a commodity. Karl Marx
Radiation doesn't recognize borders. A meltdown in Japan or India, say, is a danger to the whole world. Wind circulates the radiation everywhere. Water quality is affected. We all eat the same fish. We use products from all over the world - if something is contaminated, it will cause harm. Wladimir Klitschko
Unlike a fountain that circulates the same water in an enclosed, perpetually recycling system, a human being circulates thoughts in an unlimited reservoir of self. Don't limit yourself to being a mere fountain when you contain an ocean. Vera Nazarian
